Recent research progress in stress corrosion crack initiation of Alloy 690 in pressurized water reactor primary water

Review of Materials Research
Alloy 690 exhibits much higher resistance to stress corrosion cracking (SCC) in pressurized water reactor (PWR) primary water than other engineering austenitic alloys as it is highly resistant to penetrative intergranular oxidation.

Initiation and stagnation of room temperature grain coarsening in cyclically strained gold films

, 2019
Despite the large number of experiments demonstrating that grains in a metallic material can grow at room temperature due to applied mechanical load, the mechanisms and the driving forces responsible for mechanically induced grain coarsening are still ...

Plastic accommodation at homophase interfaces between nanotwinned and recrystallized grains in an austenitic duplex-microstructured steel

Science and Technology of Advanced Materials, 2016
The plastic co-deformation behavior at the homophase interfaces between the hard nanotwinned grain inclusions and the soft recrystallized matrix grains in a duplex-microstructured AISI 316L austenitic stainless steel is examined through the analysis of ...

Fabrication of Ultrafine Low Carbon Metallic Multilayer by Accumulative Roll Bonding

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2014
The effect of grain refinements by Accumulative Roll Bonding (ARB) was investigated on low carbon steel. Optical microscopy (OM) and microhardness tests were used to check the phase changes and hardness before and after ARB.

The nonlinear time-dependent response of isotactic polypropylene

, 2002
Tensile creep tests, tensile relaxation tests and a tensile test with a constant rate of strain are performed on injection-molded isotactic polypropylene at room temperature in the vicinity of the yield point. A constitutive model is derived for the time-
